Yes!, Once converted it's basically a factory unlocked 6T with OOS , and from there you can install all sorts of ROMs.

But, I heard that if you try, you can brick because some signature difference between T-Mobile modem/radio vs unlocked. Also, that it won't work because of that. Fastboot will throw errors

I have done it with success. I flashed the MSM 9.0.11 then fastboot flashed the current T-Mobile fastboot ROM and it worked fine.
Only issue was updates. With an unlocked bootloader T-Mobile will not get updates to flash.

Well flashing T-Mobile stock ROM would be fine. I am wondering if we can flash stock OOS with fastboot

yes, you need to be on stock brazil rom.
i RSD's brazil's 4.4.4 then did the update to 5.0.2, then manually flashed the modems. Then i flashed TWRP, so now i am sitting on a regular rooted xt1058 5.0.2 moto x. The warning people are giving is that once you do this, like previous updates, you cannot RSDlite back to a 4.4.4 build. This is not an issue for us, as we can just flash stuff within TWRP, like krypton, for example.

Need a little help please:
I'm now on cm12, flashed over stock KK rooted (twrp, unlocked BL). I have a nandroid backup of my 4.4.4 rooted made before flashing CM.
If i restore that and then go to the RSD process, will I have any problems "downgrading"?

The only "downgrade" people are talking about is bootloader version. OS version does not matter.
If you were stock KK, then you probably have the KK BL which is the most recent BL besides the 5.0.2 release. Flashing the 5.0.2 release just means you can no longer flassh the stock 4.4 SBF package because that attempts to install the older bootloader. you can still flash the rom associated with the SBF package though twrp, if that makes sense

Very risky flashing a different carriers boot loader and gpt.bin.I would just wait a little bit longer.
Again, please be aware that if you flash another carrier/model 4.4.4 and flash the brazilian OTA, DO NOT DO NOT DO NOT try to downgrade back to your original stock model/carrier 4.4.4 to take the OTA meant for your device
These instructions are fairly easy to follow and people assume it's just as easy to get back where they started but it's not, if you flash the brazilian OTA then be prepared to wait for a leaked 5.0.2 SBF for your model/carrier, there's no guarantee that it will be leaked and even if it is you have to hope that the gpt/bootloader version is the same or newer than the ones in the brazilian OTA
It does work fine but know the risks and don't expect XDA to be able to fix everything

I think i got it. Just need to be sure about BL version... I checked and it is 30.B4 but can't find a list with the versions explained...
But seems to be KK, since I did not used RSD since I flashed stock 4.4
thanks

Don't relock bootloader with MM ROM.
(if you already have N firmware, right now)
After flashing MM, you will receive OTA for N, and it will brick your device.
Do it with latest N september patch (available in guide section)

You can, but you need to remember that "don't take OTA in future, never tap update notification"
Also if you sell or give your phone to someone else, give them latest N.

Yes, fastboot commands are same.
hi! i know this is something irrelevant but since this is related to bootloader unlocking,i wanted to question that if i wanted to relock my bootloader which was on the sept 01 patch when unlocked;would i have to flash the same build from the fastboot again to relock it?and will it be safe to install ota updates after relocking the bootloader and reverting to the stock rom?

Only for taking OTA, locked bootloader is not necessary, you can take OTA with unlocked bootloader too.
things to take care of,
don't flash older firmwares than you have at the moment,
As you have september patch, flash september (while relocking too), don't downgrade.
If you downgrade, then don't take OTA. Warned..

My bad!
GPT and bootloader won't get flashed if you downgrade, it will fail, you can't flash older versions.
I don't know if it's possible to lock without flashing them, You can try flashing without GPT and Bootloader.
Just a suggestion! You don't need to flash the firmware again, if you are already on it. For eg, If you are already on Sept patch and want to relock, you don't need to flash the ROM again to relock it. Just use the fastboot commands.
I would recommend to leave it unlocked, because if anything went wrong with your device, atleast you will be able to save the data of internal memory atleast!

you can use magisk 18 also
I just recently installed b20, had trouble installing it had to oem lock and oem unlock in b15 edl then update through official recovery to get the thing to install. Well the playstore store now shows device not certified on a clean install, im guessing its because of the oem unlock.

Thanks. I was able to get back from Oreo to Marshmallow via Jcadduno's instructions in the rom/kernel sticky. Used MiFlash + B19 EDL package and then was able to get into fastboot & oem unlock.
I'd like to get to a state of stock Oreo + TWRP + Magisk. Has that combination been achieved by anyone?
Is your playstore certified? Cause on my clean install before i installed any other stuff showed device not certified.

How to update to PIE official (unlocked Bootloader with TWRP)

Guys today morning I got the OTA UPDATE to PIE. I am currently on v340 with an unlocked bootloader and TWRP already installed.
Should I go with the OTA update? Will it cause any errors?

Stay on oreo, pie is a disappointment over oreo in many ways, like BB reduced, sound quality reduced, no night light and most important you can't play PUBG in HD and many more.
If you really want to taste pie then you can use custom pie roms otherwise stay on stock oreo.

If your bootloader is unlocked then it's not a good idea to update via FOTA in my opinion. Wait for until someone made a flashable Twrp zip.

To install any rom using twrp you must download the rom and place it in your storage
Then boot into twrp
Click on install and and browse to your file click on it and flash it...
You can also do clean flash by wiping your sytem and data before flashing....
I saved update file on SD card, restarted mobile and update proces itself started.
Everything was fine.

I think I should wait till someone makes a TWRP flashable zip. Way too much hassle, again going back to stock rom using adb, then updating the rom, then installing Twrp and magisk again.

Bricked device need help

So my mi 9t is not bricked, I was running the latest EU version of miui 11 when I tried to lock the bootloader. I now have the error your system has been destroyed? But due to antiroll back protection I can't flash any of the current .tar files available for miflash tools. Is there anyway around this or will I have to wait till a miui 11 version of the flash tool images are released? Any help would be greatly appreciated!
